I sent my machine in for a battery charging issue and got it back, so I was able to check this out for you. With a new motherboard installed, I do see a great difference in hibernation time. It's not a 5x difference for me, more like 2x, which is still bad. Uninstalling the IAA solved the problem for me too.Originally posted by: jrichrds
Did installing IAA result in a significant slowdown when going into hibernation?
Without IAA, the hibernation progress bar speeds along nicely. (I'm running WinXP SP1) With IAA (either 2.2.2 or 2.3.0), the hibernation progress bar crawls along. I'd say it's 5x slower, so it's not something you'd have to time to notice. Uninstalling IAA solves the problem, so thankfully, it's not an issue that requires a reinstall of the OS to resolve. There is no difference in speed resuming from hibernation with and without IAA.
I'm trying to determine whether this is simply a characteristic of having IAA installed, or whether it's just my particular laptop configuration.
I also do not gain any performance after installing the IAA now. I've tried it with 2 different BIOS versions and have had no improvement using the IAA, only slower hibernation.
